Iii the drawings 1, is a turbineengine resting'en the bed '2 andprovided with a shaft 3, to" which shaft is secured any-"desirablepiston 4 having vanes 5. Rings of stationary vanes 6 are secured to theshell of the engine. The front end oflthe shaft is journaled in a frame7 and has a'worm 8 secured to it, which worm engages the worm wheel 9 onthe shaft 10. This worm wheel and shaft are mounted in the casing 11.,On the shaft 10, at right angles to each other, are the 'cranks 12, toeach of which is connected a connecting rod 13, the lower end of each ofwhich connects to a piston l i-of a com ression cylinder 15. The inletport 16 0 the I cylinder communicates with a carbureter 17 by means of aconnection 18, at the upper soon as the engine is in operation.

p The operation of this::mechanism-isas. follows: After theenginezhasbeen put in 176' operation by means :of ompressed air in thetank 22,2111 upward stroke of-thepiston,

.14 will draw an explosive mixture from the; carbureter 17 into thecylinder 15'. ,The pres-- 3 sure of the air in the tank 22 will: becominunicated throughthe i -e525 and :32 to the lower side of thevalve30' and hold it-in [place The. down stroke of thepiston-l t willcompress the charge whichfis exploded by means ,of the spark-plug.20as-soon as compressed. The force of .the explosion will drive down"the valve 30: permitting the burned gases to rush downlthe' passage-37,through the passage 35 and-up 'the passage 1 .36 into the engine,driving-the same. Atthe-'85 same time a part of the gas will push up thepiston 27 against the pressure in the tank. The valve 30 being ofl itsseat so' long as the pressure in the cylinder 15 exceeds that in thetank, the gases in the cylinder 26 will flow back through the passage 16and down the passage 37 as soon as the pressure in the cylinder 15diminishes When the pressure of-the burned gases onthe upper side ofthevalve 30, plus the weight of this valve, is less than the pressure onthe lower side of this valve, the valve will be forced to its seat.

It will be noticed that this compressor will have an explosion wheneverthe piston reaches the bottom of its stroke. With two compressioncylinders and pistons, there will be two explosions at each revolutionof the Any desirable valve may be substitutedfor that ,betweenthe comressor and'engineand the carbureter emp oyed will depend upon'theselection of the constructing engi neer.

Many of the details may be varied without departing from the spirit ofmy invention;

Having now explained my improvements, what L claim as my invention anddesire to secure by Letters Patent is 1. In an explosion engine, thecombination of a motor and the shaft thereof, a crank shaft actuated bythe motor shaft, compressors driven by said crank-shaft, a dischargevalve for each compressor, a pipe leading from each 'valve to saidmotor, a source of supply of explosive vapor, and a pressure equalizingdevice for said compressor comprising a chamber and'a resiliently heldpiston'therein.

'2. In an explosion engine, the combination of a turbine engine having ashaft, a worm on said shaft, a crank shaft, a worm wheel mounted thereonto engage the worm on-the turbine-shaft, a crank on each end of thecrank shaft, "two conipressicn cylinders and pistons therefor, aconnecting rod between each piston and its crank, an equalizingcylinderconnected to each compression cylin return'the piston in the equalizingcylinder.

4. In an explosion engine, the combination of an explosion motor, acompressor for fuel vapors, niechani'sm for driving said com pressor bythe motor, an equalizing chamber connected at its lower end to thecompressor,

a piston in said chamber, an air compressor, 7

and a pipe connecting the upper end of said equalizing chamber and saidair compressor.

5. In an explosion engine, the combination of a turbine, a compressordriven thereby, a discharge valve for said compressor comprising acylinder and a piston therein, an air compressor, and a pipe connectingthe air compressor and valve cylinder so the compressed air willnormally hold the valve on its seat.

6. In an explosion engine, the combination of a turbine, a fiielcompressor driven thereby, an equalizing chamber connected at itslowerend to the compressor, a piston in said equalizing chamber, an aircompressor, a pipe connecting the upper end of the equalizing chamberand the air compressor, a discharge valve between the fuel compressorand the turbine, and a air compressor to the va ve chamber.

7. Thecombination of an en ine having a shaft, fuel compression cyliners adjacent thereto, compressing pistons in said cylinders driven bysaid shaft, means to supply explosive vapors to said cylinders, an aircompressor and a receiver, a piston discharge valve at the bottom ofeach cylinder, a pipe extending from each valve to the engine, means forsupplying explosive vapor to the compression chambers, an air compressorand pipes connecting the air compressor and the discharge valve toconvey air under pressure whereby the valves are normally held on theirseats.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
